  The deaeration device 50 is a device that removes gas such as air contained in the frozen dessert mix recovered from the bulk frozen dessert molding machine 20 from the frozen dessert mix, and is a mix storage tank 51, a deaeration tank 52, and a deaeration tank 52. Is provided with a suction means 54 connected via a conduit 53. The mix storage tank 51 is a tank that stores the frozen dessert mix recovered from the block frozen dessert molding machine 20. The mix storage tank 51 is provided with a liquid level detection device 55 such as a level switch. When the frozen dessert mix in the tank 51 reaches a predetermined amount, the valve 56 is automatically opened and the deaeration tank is opened. 52 is configured so that the frozen dessert mix can be supplied.

  The deaeration tank 52 is a sealed tank that stores the frozen dessert mix supplied from the mix storage tank 51. The suction means 54 is means for sucking air in the degassing tank 52 and sucking air in the degassing tank 52 to reduce the pressure in the degassing tank. In this embodiment, for example, a vacuum pump Is adopted.

  The lower part of the deaeration tank 52 is connected to the storage part 10a of the mix cooling device 10 via the mix reflux means 60 constituted by a pumped pipe. In addition, liquid level detection devices 57 and 58 such as level switches are provided in the vertical direction above the connection portion between the deaeration tank 52 and the mix reflux means 60. When the upper limit liquid level detection device 57 detects the liquid level of the frozen confectionery mix, the valve 5 is automatically opened so that the frozen confectionery mix can be supplied to the storage unit 10a of the mix cooling device 10. When the lower lower limit liquid level detection device 58 detects the liquid level of the frozen dessert mix, the valve 59 is automatically closed so that the supply of the frozen dessert mix to the storage unit 10a of the mix cooling device 10 can be stopped. It is configured.

  A method for producing a lump frozen dessert using the thus configured frozen dessert manufacturing apparatus 1 will be described below with reference to FIGS. 1 to 3. In addition, FIG. 3 is a flowchart of the frozen confection manufacturing method. The frozen dessert manufacturing method basically includes a mix cooling step S1, a block frozen dessert forming step S2, a recovery step S3, a degassing step S4, and a mix refluxing step S5. Moreover, these series of processes are performed in aseptic conditions.

  First, the mix cooling step S1 is performed in the mix cooling apparatus 10 shown in FIG. That is, by supplying the liquid frozen dessert mix accommodated in the storage unit 10a of the mix cooling device 10 to the freezer 10b and cooling it, a fluid solid frozen dessert mix is generated. The temperature of the fluid solid frozen dessert mix produced in the mix cooling device 10 is preferably, for example, −6 ° C. to −7 ° C. from the viewpoint of ensuring the fluidity of the frozen dessert mix.

  Next, a solid frozen dessert mix having fluidity is supplied from the mix cooling device 10 to the lump frozen dessert molding machine, and the frozen dessert mix is formed to produce a lump frozen dessert (bulk frozen dessert forming step S2). Specifically, as shown in FIG. 2, the frozen dessert mix supplied to the mix introduction hole 35 of the block frozen dessert molding machine 20 is filled in the recesses 24 and 25 of the hot water roll 21 and the pin roll 22, respectively. At this time, the air in the recesses 24 and 25 is guided to the outside through the discharge paths 34 and 34 of the filling member 23 and discharged as shown by arrows C and D. Therefore, the recesses 24 and 25 Air is not mixed in the frozen dessert mix filled in. Moreover, since the rod 31 of the pin roll 22 retreats to the inside of the pin roll 22 from the bottom of the concave portion 25 and is in contact with the disk 28, the frozen dessert mix is filled into the entire concave portion 25 in a hemispherical shape. Further, the frozen dessert mix is not filled only in the recesses 24 and 25 but also in the discharge passages 34 and 34.

  The frozen dessert mix filled in the corresponding concave portions 24 and 25 of the hot water roll 21 and the pin roll 22 is formed integrally when the concave portions 24 and 25 pass through the adjacent portions of the hot water roll 21 and the pin roll 22 to form a spherical lump frozen dessert. It is formed. At this time, since the frozen dessert mix is raised outside the recesses 24 and 25, they are brought into contact with each other with a strong force and are completely integrated.

  Since warm water is continuously supplied to the inside of the hot water roll 21 and the concave portion 24 of the hot water roll 21 is heated, the lump-shaped frozen dessert that is integrated into a spherical shape is easily separated from the concave portion 24 of the hot water roll 21. ing. On the other hand, since the inside of the recess 25 of the pin roll 22 is cooled by the block frozen dessert, the block frozen dessert is difficult to be separated from the inside of the recess 25 of the pin roll 22. Therefore, the spherical lump frozen dessert moves downward as the pin roll 22 rotates while being accommodated in the recess 25 of the pin roll 22. When the rod 31 provided inside the pin roll 22 hits the cylinder 29 and protrudes into the recess 25, the block frozen dessert pushed by the outer end of the rod 31 falls from the recess 25 and is discharged.

  The bulk frozen confection thus formed is then subjected to a rapid cooling process in which, for example, it is frozen by being submerged in liquid nitrogen, and then subjected to a coating process for coating the surface of the bulk frozen confectionery as a product. Complete.

  On the other hand, the frozen dessert mix accumulated in the discharge passages 34 and 34 is a remaining frozen dessert mix that has not been used for forming the spherical lump frozen dessert, and is recovered by the recovery device 40 through the remaining mix discharge holes 36 and 36 (recovery Step S3), and stored in the mix storage tank 51. Thereby, it is possible to prevent the discharge passages 34 and 34 from being clogged with the frozen dessert mix, and to reliably release the air when the frozen dessert mix is filled in the recesses 24 and 25 of the hot water roll 21 and the pin roll 22. can do.

  The frozen dessert mix recovered from the discharge passages 34 and 34 by the action of the recovery device is melted and liquid while passing through the remaining mix discharge holes 36 and 36 and the conduit 40 or while being stored in the mix storage tank 51. It becomes a frozen dessert mix. Moreover, since the collection | recovery apparatus 40 will also attract | suck air in addition to frozen dessert mix through the residual mix discharge holes 36 and 36, air melts in the frozen dessert mix collect | recovered by the collection | recovery apparatus 40 in large quantities. At the same time, bubbles are mixed.

  When a predetermined amount of frozen dessert mix accumulates in the mix storage tank 51, the liquid level detection device 55 detects the liquid level of the mix and automatically opens the valve 56 to remove the stored frozen dessert mix of the deaeration device 50. The deaeration tank 52 is supplied.

  The frozen dessert mix guided to the degassing tank 52 is degassed in the degassing tank 52, and the gas contained in the frozen dessert mix is removed (degassing step S4). Specifically, the air in the deaeration tank 52 is sucked by the action of the suction means 54 to reduce the pressure in the deaeration tank 52, thereby promoting the bubble formation of the dissolved gas dissolved in the frozen dessert mix. And deaerate. The bubbled dissolved gas and the gas originally present as bubbles in the frozen dessert mix rise to the liquid level of the frozen dessert mix, and are sucked by the suction means 44 and discharged to the outside. In this deaeration process S4, the deaeration process is performed to a frozen dessert mix, and the deaerated frozen dessert mix is produced | generated.

  After the degassing step S4 is completed, the frozen dessert mix from which the gas contained in the frozen dessert mix has been removed is returned to the storage unit 10a of the mix cooling device 10 by the action of the mix refluxing means 60 (mix refluxing step S5). At this time, since the upper limit liquid level detection device 57 and the lower limit liquid level detection device 58 provided in the deaeration tank 52 are supplying the frozen dessert mix to the mix cooling device 10 while controlling the liquid level of the frozen dessert mix, The situation where the liquid level of the frozen dessert mix in the deaeration tank 52 is located below the mix reflux means 60 can be avoided, and the air in the deaeration tank 52 is erroneously supplied into the mix cooling device 10. Can be prevented.

  The degassed frozen dessert mix returned to the mix cooling device 10 is cooled again in the mix cooling device 10 to be generated into a fluid solid frozen dessert mix, and then supplied to the block frozen dessert molding machine 20. It is formed into a lump frozen dessert. The bulk frozen dessert manufactured by reusing the degassed frozen dessert mix contains almost no air bubbles inside, and is difficult to break.

  Thus, according to the frozen dessert manufacturing apparatus 1 which concerns on this embodiment, even if it reuses the frozen dessert mix collect | recovered from the massive frozen dessert molding machine 20, since it can manufacture the massive frozen dessert which is hard to break, While preventing the production failure, the frozen confectionery mix can be reused to efficiently produce a massive frozen confectionery.

  In addition, since the mass frozen dessert manufactured by the frozen dessert manufacturing apparatus 1 according to the present embodiment does not include air bubbles, the frozen dessert mix is reused without degassing the conventional dessert mix. Thus, the specific gravity is higher than that of the block frozen dessert produced. As a result, even if the frozen frozen dessert is submerged in liquid nitrogen and subjected to a freezing treatment, the frozen frozen dessert does not sink in the liquid nitrogen, and the entire frozen frozen dessert cannot be frozen. Generation | occurence | production can be prevented and it becomes possible to maintain the quality of the block frozen dessert which performed the freezing process.

  Moreover, even if it is a case where the coating process which coat | covers the coating agent like a glaze agent, etc. is performed on the whole surface of the said block frozen dessert, giving a vibration to the block frozen dessert which performed the freezing process mentioned above, and rolling. It is possible to effectively prevent the occurrence of a situation in which the lump frozen dessert breaks due to the impact received when the frozen dessert rolls, and the lump frozen dessert can be efficiently manufactured.

  In addition, as in the past, mass frozen desserts manufactured by reusing the frozen dessert mix without degassing the dessert mix contain a lot of air bubbles and almost no air bubbles. The product quality varies, but according to the frozen dessert manufacturing apparatus 1 according to the present embodiment, the mass frozen dessert containing almost no air bubbles can be produced, and therefore the product quality varies. Can be prevented.

  As mentioned above, although one Embodiment of this invention was described, the specific aspect of this invention is not limited to the said embodiment. For example, although the structure which guides the frozen dessert mix collect | recovered from the lump frozen dessert molding machine 20 to the mix storage tank 51 is employ | adopted, the deaeration tank 52 of the deaeration apparatus 50 directly selects the frozen dessert mix collect | recovered from the lump frozen dessert forming machine 20. It is also possible to adopt a configuration that leads to By adopting such a configuration, the installation space of the frozen dessert manufacturing apparatus 1 can be reduced.

  Moreover, in this embodiment, the mix cooling apparatus 10 is prepared for the situation where air bubbles are generated on the liquid surface of the frozen dessert mix returned from the mix reflux means 60 to the storage unit 10a of the mix cooling apparatus 10. 4, the structure which connects the suction means 70 which attracts | sucks the bubble 76 which arises in the liquid level 75 of the frozen dessert mix accommodated in the storage part 10a to the storage part 10a may be employ | adopted. In FIG. 4, an ejector pump is illustrated as the suction means 70. This ejector pump forms a negative pressure at the tip end 72 of the nozzle by allowing compressed air to pass through the upper portion of the nozzle 71 as indicated by arrow E, and the liquid level of the frozen dessert mix using this negative pressure. 75 bubbles 76 are sucked up from the suction port 73 of the nozzle as indicated by an arrow F and discharged to the outside together with the compressed air. In addition, as the suction means 70, the air bubbles 76 may be sucked and removed by using a vacuum pump in addition to the ejector pump.

  With such a configuration, when the frozen dessert mix supplied from the mix reflux means 60 is accommodated in the storage unit 10a, even if air bubbles 76 are generated, the air bubbles 76 are sucked and removed by the suction means 70. Therefore, it is possible to reliably prevent air bubbles from being generated in the solid frozen dessert mix having fluidity generated in the mix cooling device 10 and to efficiently produce a lump frozen dessert that is difficult to break. Can do.

  Further, from the viewpoint of efficiently removing bubbles 76 generated on the liquid level 75 of the frozen confectionery mix, it is preferable to control the operation of the suction means 70 in conjunction with the liquid level control of the frozen confectionery mix. Specifically, for example, a liquid level detection device such as a level switch (not shown) is provided in the storage unit 10a, and the liquid level of the frozen dessert mix supplied from the mix reflux means 60 to the storage unit 10a of the mix cooling device 10 is When the installation position of the suction port 73 of the suction means 70 is reached, the supply of the frozen dessert mix is stopped, and the suction means 70 is operated to automatically remove the bubbles 76 generated on the liquid surface 75 by suction. Is preferred.

  Further, in the present embodiment, a depressurization type deaeration device in which a deaeration tank 52 and a suction means such as a vacuum pump are combined is adopted as the deaeration device 50, but the present invention is not particularly limited to such a configuration. For example, a gas membrane separation device that removes gas contained in a frozen dessert mix with a gas-liquid separation membrane that allows gas to pass but not liquid, and an ultrasonic deaeration device that removes gas contained in the frozen dessert mix by ultrasonic vibration It can also be adopted. Moreover, the deaeration apparatus 50 can also be comprised by combining a pressure reduction type deaerator, a gas membrane separator, and an ultrasonic deaerator.

  Moreover, in this embodiment, although the apparatus which forms spherical lump frozen dessert is employ | adopted as the lump frozen dessert molding machine 20, for example, the lump frozen dessert molding machine which shape | molds elliptical spherical or cubic-shaped lump frozen dessert other than spherical shape Can also be adopted.

  In the present embodiment, the suction action of the pump for decompressing the inside of the pin roll 22 of the bulk frozen dessert molding machine 20 is sucked from the recess 25 into the pin roll 22 through the gap between the rod 31 and the guide hole 30. It is also possible to adopt a configuration in which the remaining frozen dessert mix that has not been used for the formation of the bulk frozen dessert is guided to the recovery device 40. With such a configuration, the frozen dessert mix can be reused efficiently.

  Further, as shown in FIG. 5, as a pump for decompressing the inside of the pin roll 22 of the bulk frozen dessert molding machine 20, the pump 41 of the recovery device 40 is used together, and the pump 41 and the inside of the pin roll 22 are connected to the pipe 43 You may employ | adopt the structure connected through this. With such a configuration, the remaining frozen dessert mix sucked into the pin roll 22 from the recess 25 through the gap between the rod 31 and the guide hole 30 can be recovered via the pipe line 43, and the frozen dessert manufacturing apparatus 1 can be reduced in size and equipment cost.
